x: A tidymatrix object with rows or columns active
center: If TRUE (default), center to mean = 0
scale: If TRUE (default), scale to sd = 1

Value

A tidymatrix object with scaled matrix

Examples

mat <- matrix(rnorm(20, mean = 10, sd = 5), nrow = 4, ncol = 5)
tm <- tidymatrix(mat)

# Scale rows (z-score per row)
tm_scaled <- tm |>
  activate(rows) |>
  scale()

# Scale columns
tm_scaled <- tm |>
  activate(columns) |>
  scale()

# Only center, don't scale
tm_centered <- tm |>
  activate(rows) |>
  scale(center = TRUE, scale = FALSE)
